A search of Dallas police records has revealed a series of car crashes caused by officers using in-car computers while driving. But despite those incidents, Dallas Police Chief David Brown has decided not to implement a written policy to prohibit officers from typing while driving.

Through an open records request, the NBC 5 Investigates team found Dallas police officers in two years caused 168 crashes that the department classified as "preventable." Thirteen of those crashes involved distractions in a police car, while eight of those 13 crashes involved officers typing on computers, according to police records.

Police department videos obtained by NBC 5 Investigates show some officers driving off of roadways and damaging their cars while using computers. In one video, an officer rear ends another driver at a stoplight while typing a message.

In June top Dallas police commander Deputy Chief Rick Watson said the department was "looking at revising" its policy on computer use while driving in hopes of preventing crashes.

Fort Worth police plan to test a new device that limits an officer's ability to use a computer while a police car is moving. A five-month investigation by NBC 5 uncovered dozens of crashes in North Texas involving officers distracted by computers. (Published Wednesday, Jan. 30, 2013)

A Dallas police spokesman now says those changes are not going to happen.

"We train our officers on the danger of distracted driving," said Lt. Paul Stokes. "We believe if we train officers well, they will use good judgment."

NBC 5 Investigates wanted to ask Brown why he's not going to implement tougher policies or technology to keep officers and other drivers safe, but a department representative said the chief would not answer questions and that there would be no more discussion about the issue.

Because Brown is a public official, NBC 5 Investigates told the department that if the chief would not meet, the team planned to approach him at a public event to ask him about this issue. NBC 5 Investigates did so at a police department graduation.

At first, Brown said he would answer the question, but then accused NBC 5 Investigates of ambushing him, being disrespectful to him and his staff and insulting people in the room by showing up to talk with him at a public event that the media was invited to. He suggested that NBC 5 has treated him differently than previous police chiefs.

"There's a level of respect that I've seen in my 30 years as a police officer here that predecessors of mine hadn't received from your station, and so my big question is, why are you treating my administration differently with the ambush here today at a police graduation?" Brown said.

Kim Schlau said she believes police departments that don't take a tougher stand on distracted driving are bound to repeat tragedies such as the one that devastated her family.

"Something is going to happen. It's inevitable," Schlau said.

In 2007, her daughters, Jessica and Kelli Uhl, were killed by an Illinois state trooper. The trooper was driving more than 100 mph while responding to a call and admitted he was talking on a cellphone and emailing on his police computer moments before the crash.

"I don't want anyone else to go through what we went through as a family, telling us our children weren't coming home," Schlau said.

After her daughters died, the Illinois state police implemented new policies.

Schlau said she believes too many departments wait until after a tragedy and fail to see the warning signs in minor crashes.
